摘要： A method of pressure control for transmissions having a hydraulic circuit selectively communicating with first and second pumps via first and second regulators includes commanding communication to the hydraulic circuit to transition from the first to the second pump and the PCS to set the regulators to a high pressure-regulation level. The hydraulic circuit line pressure is raised to an elevated value exceeding a target value. The line pressure is lowered from the elevated to the target value at or after completing the transition to the second pump. The method may include transitioning communication with the hydraulic circuit from the second to the first pump. The PCS maintains the regulators at the high level and line pressure is raised to the elevated value. PCS sets the regulators to a low level, and line pressure returns to the target only at or after completing the transition to the first pump.

摘要： A method of operating a hybrid powertrain includes commanding an engine start of an engine configured to operate at approximately zero engine speed. A spooling phase includes accelerating the first electric machine with the first machine torque, such that the first electric machine begins rotating. The first machine speed increases in magnitude from zero to non-zero, but engine speed is maintained at approximately zero. The mechanical energy of the rotating first electric machine is stored. A transfer phase includes commanding an increase in magnitude of the first machine torque and decelerating the first electric machine, such that the first machine speed decreases. The stored mechanical energy of the first electric machine is transferred to the engine to increase the engine speed to greater than zero, such that the engine starts.
